You work for a music production company and are creating a new audio ad campaign for an album release. You're having an issue with the campaign and need to identify the cause. Within Display & Video 360, what could the potential issue be?

Display & Video 360 (DV360) audio ads require source files to be in either MP3 or OGG format. WAV files are uncompressed and generally too large for efficient serving in digital advertising platforms, leading to potential issues with ad delivery or campaign setup. Therefore, a WAV file would be an incompatible format. The other options are incorrect: One of the ads is missing a companion creative: While companion creatives are common for audio ads, their absence typically wouldn't prevent the campaign from running entirely; it would just mean the visual component is missing. One of the source files is in MP3 format: MP3 is a supported and commonly used audio format for DV360 audio ads. One of the ads was created in Ad Canvas: Ad Canvas is a creative tool within DV360 for building various ad types, including audio ads, so this would not be an issue.
